Title: Innovations by James W Sinclair
Introduction
James W Sinclair is a notable inventor based in Logan, UT (US). He has made significant contributions to the field of materials science and engineering, particularly in the preparation and bonding of materials used in various applications.
Latest Patents
James W Sinclair holds 2 patents that showcase his innovative approaches. His first patent, titled "Method of surface preparation of aluminum substrates," describes a surface preparation process that enhances the bond strength, fracture toughness, durability, and failure mode of adhesive bonds on aluminum and aluminum alloy substrates. This process reduces the sensitivity of aluminum substrates to processing variables such as humidity and temperature, thereby improving processing timelines. The method involves treating the aluminum surface with a solution of an alkali metal metasilicate, followed by a treatment with an organofunctional silane solution.
His second patent, "Methods and compositions for bonding propellants within rocket motors," presents a system for binding rocket motor propellants directly to the insulation layer within the rocket motor. This innovative method eliminates the need for a liner layer between the insulation and the propellant. The process involves coating the insulation layer with a reactive material, such as isophorone diisocyanate (IPDI), which penetrates the insulation layer. Once sufficient penetration is achieved, the hydroxy-terminated polybutadiene-type (HTPB) propellant is applied, forming a strong bond between the insulation and the propellant.
